f(**kwargs)

This behavior seems pretty strange to me, indeed PyPy gives the
TypeError for both attempts. I just wanted to confirm that it was in
fact intentional.
I ran into same issue with Django on Jython yesterday [1] since Jython
too gives TypeError for 'dict({}, **kwargs)'.

[Python-Dev] Returning exception stack trace in SimpleXMLRPCServer response
Hi, When an exception occurs in a function, SimpleXMLRPCServer currently sends exception type and value back to the client (in faultString) . So the client sees some thing like: 'type \'exceptions.ValueError\':invalid literal for int() with base 10 This string is constructed in _marshaled_dispatch() as %s:%s % (exc_type, exc_value). How about adding the stack traceback to this string? I found it very useful to have the server side traceback in case of failures. I will come up with a patch if there is any interest.

Re: [Python-Dev] os.rename on windows

And, POSIX.1 says, If newpath already exists it will be atomically replaced (subject to a few conditions; see ERRORS below), so that there is no point at which another process attempting to access newpath will find it missing. Clearly, unliking and then calling MoveFile is not atomic. So, cygwin is not being honest here because in these less frequent cases, the rename will not be atomic. You are right.

[Python-Dev] os.rename on windows
Hi, I have submitted a patch (http://www.python.org/sf/1704547) that allows os.rename to replace the destination file if it exists, on windows. As part of discussion in the tracker, Martin suggested that python-dev should discuss the change. Currently, os.rename() on windows uses the API MoveFile() which fails if the destination file exists. The patch replaces this API with MoveFileEx() and uses the flag MOVEFILE_REPLACE_EXISTING which causes the destination file to be replaced if it exists. However, this change is subtle and if there is any existing code that depends on current os.rename behaviour on windows, their code is silently broken with (any) destination file being overwritten. But the functionality of replacing is important and I would like to know the best of way of supporting it. If it is deemed that this change is not good to go in as-is, how about having an optional parameter to os.rename (say, win_replace) that can be used by callers to explicitly request replacing? I must also point out that the patch uses another flag MOVEFILE_COPY_ALLOWED effectively allowing renamed files to be on separate file systems. The renaming in this case is not atomic and I used this flag only to support current functionality. It is not a bad idea to disallow such renames which brings it in line with the behaviour on many unix flavors. This also has the potential to break code but not silently. Lastly, I found an old discussion about the same topic by this list. http://mail.python.org/pipermail/python-dev/2001-May/014957.html Even though Guido indicated that he doesn't support API change in this thread, I am posting again as I did not see any one mention MoveFileEx() in that thread.

Re: [Python-Dev] os.rename on windows
On 4/30/07, Andrew Bennetts [EMAIL PROTECTED] wrote: Does MOVEFILE_REPLACE_EXISTING mean the rename over an existing file is actually atomic? I cannot find any MSDN docs that say so (and I've seen some that suggest to me that it probably isn't). Even though MSDN docs do not say it explicitly, I found some discussions claiming that MOVEFILE_REPLACE_EXISTING is atomic. However, after seeing your comment, I did a more thorough search and I too found some references claiming otherwise. As a last resort, I checked cygwin documentation which claims that it's rename() is POSIX.1 compliant. If I am not mistaken, POSIX.1 does require atomicity so I am curious how rename() is implemented there. I checked out the sources and I will try to find more about their implementation. I completely agree that without positive proof of atomicity, there is no point in making this code change. Also, I assume this cannot replace files that are in use? A simple test shows that it can indeed replace files that are open.
